This probably belongs in the "Holsters & Accessories" forum, but....
I'm a skinny guy and a tuckable IWB works just great for me, as long as I blouse my shirt appropriately. I personally have a Crossbreed Supertuck (www.crossbreedholsters.com), but there are many companies with similar designs, including:
www.comptac.com (Minotaur & C-TAC)
www.usgalco.com (King Tuk)
The above typically cost $70 and up. If low cost is a main priority and you're fairly "handy," Old Faithful sells kits of a very similar configuration, which cost about half of the assembled holsters named above. http://oldfaithfulholsters.com/categ...-holster-kits/ Personally, I don't like the way the kydex doesn't attach directly to the leather on this design, but that's just me.
